COVID-19 疫苗的群体免疫效应：约半数避免的感染与四分之一住院和死亡归因于接种者对未接种者的间接保护
Vaccines not only directly protect vaccinated individuals but also contribute to protecting the entire population via indirect herd-immunity benefits. Half of averted COVID-19 infections and 1/4 of hospitalizations and deaths were attributable to indirect protection of unvaccinated by vaccinated.
导读
一项研究称，COVID-19 疫苗除直接保护接种者外，还经群体免疫间接保护未接种者，约半数避免的感染与四分之一住院和死亡可归因于"接种者对未接种者的间接保护"。该结论以 Reddit 科普帖在 r/science 传播并引发两极化讨论：部分高赞评论盛赞 mRNA 疫苗为重大突破，另一些则将接种率低迷归因于信任破裂与政治极化。帖中数值为研究结论的二次传播，原始文献与模型口径需回查核对。
